First flogger! Help me choose.

I have never used a flogger or whip before and want to start out with something under $20 to try it out and see how my partner and I like it. I think it will go well, but I just don't want to spend too much. Which of these do you think it the best first choice? Or perhaps you can link me to another one you liked? None of them seem like total duds and it's hard to tell the difference!
